Hollow body made of flexible plastic

The invention relates to hollow bodies made of flexible plastic, in particular according to the blow molding process with additional parts Canisters, containers, buckets, cans that can be manufactured in one piece or

Hollow bodies made of flexible plastic are already known, e.g. canisters, buckets, boxes, which are known per se Blow molding are made. In these hollow bodies protruding handles are rigid and cannot be folded down co-formed or corresponding recesses or eyelets are provided in the finished shaped workpiece, In which additional handles or lifting lugs to be produced can be folded down.

These hollow bodies with the above rigid carrying handles are very poorly suited for stacking because they can be e.g. cannot stand on top of each other or only with intermediate layers.

In contrast, the fold-down handles that are subsequently attached are expensive and complicated to manufacture. It also requires several work steps until, for example, a canister is ready for the crew.

It is also known to provide recesses in hollow bodies with rigid, protruding Ciriffen, which are then used when stacking pick up the protruding handles. This stackability but then comes at the expense of the effectively usable fill volume the hollow body.

The invention has the object of producing a blow molding process or a similar process and having handles provided, easily stackable hollow body with a better use of the filling volume cheaper than the known and can be produced in one operation.

The invention solves this problem in that the additional part is automatically erected in the position of use and when the hollow body is in the stacked position, the handle is folded down and recessed. For the invention it is also of importance that the folded handle above the outline of the hollow body protruding into a co-formed Recess of an adjacent, touching hollow body of the same type protrudes.

Another feature of the invention is that the folded handle of the hollow body engages in a locking manner in the recess of the respectively adjacent hollow body which is in contact with it. In addition, another feature of the invention is that different handles and recesses that match the handles are provided on different side surfaces of the hollow body. Modified to this, another advantage of the invention is that the handles are eyelets for hoists . According to a further inventive concept, the handles can be folded around film hinges which are formed by corners and / or transitions made thin in the material. It is also advantageous for the invention

that the handles are hand-shaped. According to Another important idea of the invention is formed by the bars of the handles and / or the handles themselves - Erected - an approximately right angle to the hollow body surface carrying it. Finally, there is another Mei kmal of the invention still in the fact that the webs of the handles and / or the handles themselves - erected form an angle with the hollow body surface carrying them, that is less than 90 and greater than 30.

In the drawing, the invention is shown in detail using exemplary embodiments. Show it:

1 shows a middle section lying in plane I-I two jerry cans placed one on top of the other,

FIG. 2 shows a view of the canisters from FIG. 1 rotated by 90;

3 shows two side by side and carrying handles containers to be sealed,

FIG. 3 is a perspective view of the container according to FIG.

FIG. 5 shows a container which, as a modification of FIG. K, has an asymmetrically arranged handle, and FIG

Fig. 6 shows a container with uinkl appbar en eyelets for hoists.

In Fig. 1 and 2, two canisters 1 made of flexible plastic are aligned with one another. For a better understanding, they are shown in section in a vertical center plane in FIG. 1. Each dex canister 1 has an outlet that is set lower on a level 2. 3, and on top of h \ and the bottom 5 in a running direction of the sectional plane 7 shallow groove 8 UNR) · 9 in the groove 8, a hand mitgeformter meet with the canister in its manufacture · carrying handle 10 is provided. Its corners 11, 12, 13 ι I ^ are made of thinner material than the rest of the cross section of the handle Iu, so that film hinges 15, 10, 17, 18 arise at these points, by means of which the handle 10 - can be folded down - without breaking can, so that, as shown in the case of the lower canister 1, an approximately flat parallelogram images.

The film hinges of the handle can also be prepared subsequent to the Herstellvcrfahre.il of the hollow body, namely in that the infr _o e points coming through a Ka It- or thermoforming (Pi eiivoi \ jan _ö j to the appropriate strength v ^r errin _o be ert. through this Prcßvorgang

the molecular structure of the plastic is aligned so that it is precisely in this treated by the pressing Zones have a much higher buckling strength and tensile strength of the material can be achieved than it is given in the full, thick material.

Ü3r handle 10 is set in its strength to the depth of the groove 8 that it can be completely retracted into it when folded. When stacked canisters however, it is by the material saving iiung in the film hinges I5 to I8 pushed up somewhat and is shown in Figure 1 and 2, then on the upper Cirund the groove 9 unloaded ^at · I ^"1 state, the handle by ^d. .E te cerialspannung pressed up so that its side legs protrude approximately vertically from the top surface 4 of the canister and the canister is "ready to hand" at all times. The handle 10 engaging in the lower groove 9 prevents the upper canister 1 from sliding against the side relative to the lower canister stacked as if they had a whole flat shape and surface.

In Fig. 3 is a section of two adjacent containers 19 is shown in a k by the straight line 20 of FIG. Continuous vertical plane. The containers 19 are shown in perspective in FIG. K , wherein they have been moved apart for the sake of better understanding.

On the top of the container two transverse grooves 22 and 22 are provided, in the middle of which in the longitudinal direction of the container a handle 23 or 24, which can be folded down around film hinges 25 and 26 transversely to the longitudinal direction of the container, was formed during the manufacture of the container. The handles 23 « 2k are designed in their height so that they - when folded - protrude over the edge of the container. In the case of two containers 19 (Fig. 3) which are lined up with their long sides, the protruding, folded handles 23, 24 of one container engage in the groove 21 or 22 of the other container the container surfaces can, since the handles 23 » 2k are folded down and recessed, further, different types of container can be divided.

Modifying the grooves in the grooves 21 of the container, additional projections 38 are provided, which make it possible to to lock one container with an adjacent one. The projections 38 are pointing towards the handle 23 on their Surface 39 slightly undercut. The inner clear height of the handles 23 is chosen so that two Containers are locked together by folding a handle of one over and locking it into place over the protrusion is printed in the groove 21 of the other container.

In this way, preferably narrow, long and tall containers are stacked relatively light and stable and be stored.

Modifying this, FIG. 5 shows a wide container 27, on the surface of which a handle, which can be folded over laterally around film hinges 29 in a transverse groove 28, is arranged eccentrically. At the end of the groove 28 facing away from the handle, a projection 31 acting in a manner similar to that in FIGS. 3 and k is arranged centrally. The distance between the inner surface 32 of the projection 31 and the handle is dimensioned, for example, so large that the handle 30 can also be folded over in the direction towards the projection 31 and sunk into the groove 28.

When storing the same containers 27, these can be connected to one another with the aid of the handles 30 and the projections 31 be locked. If the container 27 is stored with containers that are dissimilar to it, e.g. other containers on its surface Container stored, so the handle 30 »without interfere and without protruding from the side, in which the container's own groove 31 is sunk.

jLii Fig. 6 is a _ö jOÜv oiui.iigen s container 33 shown the upper part. On its upper side Jk there are eyelets 35 for hanging hats or other means of a hoist. These loops are preferably in at the side Jk O at the container 33 üe _o forming indentations 36 obliquely, for example below 75 ° ^ ^U1 surface of the top Jk inclined angeci'dne \. U ^ - cn the arrangement in the indentations 36 and on &"and the inclination of 75 ° is selected on the one hand that the lifting tool can easily be hooked into the upstanding ous 35 and that the eyelets 35" if other containers or objects on the Surface of the container are automatically folded and sunk into the indentation 36, and cannot be folded back and crushed or torn,

If another container is placed on container 33, which in its ßodenfläche the same indentations as the iti of the surface of the dehältis 33 and described at the same distance from one another, then when the indentations run one above the other, the eyelets 35 become due to the elastic tension in the Füinscharnieren 37 pressed into the upper indentations (similar to Figs. 1 and 2), whereby the upper container is immovable against the lower one is held.

Carrying handles and üsen according to the invention can be used for all Manufacturing processes in which bodies or struts be formed coherently with additional parts (bias, Injection, liieii), Preü, deep-drawing or similar processes) made of elastic material (plastic, metal, Uuiiiini or the like), be shaped. It is also conceivable that such handles with elastic Füinscharnieren subsequently by welding, Gluing, riveting, etc. to hollow bodies or the like.
